The movie centers on a discovery made by Christian (Robert Hoffman) and his girlfriend on what was meant to be a romantic stroll. At first, the couple happens on what appears to be a corpse, but upon further inspection, they see that the woman is still alive. As luck would have it, Christian meets the strange woman (Suzy Kendall) on a yacht party several days later, and quickly finds himself tangled in an affair. During a hotel room tryst, another man breaks in and savagely beats Christian. Quite accidentally, Christian ends up shooting the intruder with his own gun. In what is perhaps the most bizarre twist of events thus far, the body disappears, leaving Christian in the middle of yet another mystery.
